VideoDevice System Object Overview

The Image Acquisition Toolbox™ introduces the VideoDevice System object™,
which allows single-frame image acquisition and code generation from MATLAB®.

You use the imaq.VideoDevice function to
create the System object. It supports the same adaptors and hardware
that the videoinput object supports; however, it
has different functions and properties associated with it. For example,
the System object uses the step function to acquire
single frames.
